With growing global competition, the process industries must spare no effort in insuring continuous process improvement in terms of  Increasing profitability; Conservation of resources and Prevention of pollution.The question is how can engineers achieve these goals for a given process with numerous units and streams? Until recently conventional approaches to process design and operation put emphasis only on individual units and parts of the process. A more powerful integrated approach was lacking. The new field of Process Integration looks towards the processing plant as a whole in its attempt to find solutions and improvements. Research over the past two decades has resulted in many techniques that allow engineers to better understand complex facilities and significantly enhance their performance. This textbook presents a comprehensive and authoritative treatment of the concepts, tools and applications of Process Integration. Emphasis is given to systematic ways of analyzing process performance. Graphical, algebraic and mathematical procedures are presented in detail. In addition to covering the fundamentals of the subject, the book also includes numerous case studies and examples that illustrate how Process Integration is solving actual industrial problems.- Systematic methodology for analyzing the process as an integrated system, identifying global insights of the process, and generating optimum strategies and solutions- Proper mix of fundamental principles, insightful tools, and industrial applications- Generic techniques that are applicable to a wide variety of processing facilities- Packed with case studies, practical tools, charts, tables, and performance criteria- Extensive bibliography to provide ready access to process integration literature- Excellent review of state-of-the-art technology, development trends, and future research directions

The environmental impact of industrial waste is one of the most serious challenges facing the chemical process industries. From a focus on end-of-pipe treatment in the 1970s, chemical manufacturers have increasinglyimplemented pollution prevention policies in which pollutants are mitigated at the source or separated and recovered and then reused or sold.This book is the first to present systematic techniques for cost-effective pollution prevention, altering what has been an art that depends on experience and subjective opinion into a science rooted in fundamental engineering principles and process integration. Step-by-step procedures are presented that are widely applicable to the chemical, petrochemical, petroleum, pharmaceutical, food, and metals industries.Various levels of sophistication ranging from graphical methods to algebraic procedures and mathematical optimization, numerous applications and case studies, and integrated software for optimizing waste recovery systems make Pollution Prevention through Process Integration: Systematic Design Tools a must read for a wide spectrum of practicing engineers, environmental scientists, plant managers, advanced undergraduate and graduate students, and researchers in the areas of pollution prevention andprocess integration.- Allows the reader to establish pollution-prevention targets for a process and then develop implementable, cost-effective solutions- Contains step-by-step procedures that can be applied to environmental problems in a wide variety of process industries- Integrates pollution prevention with other process objectives- Author is internationally recognized for pioneering work in developing mass integration science and technology

The International Conference on the State of the Art on Biogas Technology, Transfer and Diffusion was held in Cairo, Egypt, from 17 to 24 November 1984. The Conference was organized by the Egyptian Academy of Scientific Research and Technology (ASR T), the Egyptian National Research Centre (NRC), the Bioenergy Systems and Technology project (BST) of the US Agency for International Development (US/AID) Office of Energy, and the National Academy of Sciences (NAS). A number of international organizations and agencies co-sponsored the Conference. More than 100 participants from 40 countries attended. The purpose of the Conference was to assess the viability of biogas technology (BGT) and propose future courses of action for exploiting BGT prospects to the fullest extent. The Conference emphasized a balanced coverage of technical, environ­ mental, social, economic and organizational aspects relevant to biogas systems design, operation and diffusion. It was organized to incorporate experiences that are pertinent, for the most part, to developing countries. In addition to the wide spectrum of presentations and country programs, structured and non-structured discussions among the participants were strongly encouraged in thematic sessions at round-table discussions, and through personal contacts during poster sessions and field trips. It was clear from the enthusiastic response of most participants that the Conference, in large measure, succeeded in fulfilling its mission. Although draft papers were distributed to all participants, it was felt that the results obtained were worthy of organized and refined documentation. And this is precisely what this book intends to do.
